What it is
A water-soluble extract derived from the dried root of Rubus coreanus, a species of raspberry traditionally used in East Asian herbal medicine.
How it works
The extract contains polyphenols and flavonoids that can neutralize free radicals, potentially reducing oxidative stress on the skin. It may also have mild anti-inflammatory effects by calming certain skin signaling pathways.
Pros

Provides a mild shield against free radicals without irritating sensitive skin, making it a safe addition to daily routines.
Soothing potential
May help calm redness or irritation, offering a subtle anti-inflammatory effect for reactive skin.
Cons and cautions
Limited research
Most evidence comes from lab or traditional use, not large human trials, so its real-world benefits are not fully confirmed.
Low typical concentration
Often used at low levels in formulas, meaning the antioxidant effect may be weaker than more established ingredients like vitamin C.
Best for
- Anyone looking for a gentle antioxidant boost
- Sensitive skin types who want to avoid stronger actives
